E3 2018: Mario Tennis Aces Adding Koopa Troopa and Blooper to Roster

Nintendo shared the news during Treehouse Live today at E3. Players who participate in the July online tournament and earn enough points can unlock Koopa Troopa early. The character will then be made available to everyone via a free update on August 1.

This will be the first time Blooper has been featured as a playable character in the Mario Tennis franchise. The last time Koopa Troopa appeared as a playable character was on the GameCube in Mario Power Tennis.
